The fictional American town of Springfield in the Simpsons is located in an impossible to determine U.S. state.
The writers of the show have deliberately made it ambiguous, a sort of Anywhere, U.S.A., and the town itself seems to change geographically to fit individual plots.
It’s been Hollywood-like, a port town, a gritty metropolis, a gambling mecca, a historical colonial town, and just about everything else.
Its radio station starts with K, which in the real world would mean that it’s west of the Mississippi River.
It has a nuclear power plant, a Russian ethnic section, and its own baseball team, yet it’s small enough to hold town meetings in a town hall.
